ALBERT PAUL SIMMONS INVENTOR.

ATTORNEY United States Patent Oflice 3,169,255 (I'GhiElNEIB HAMit EER AND PUNCH Albert Paul Simmons, Burnside, ill. Filed May 14, ISS, Ser. No. 280,201 6 Claims. (ill. 7--8) This invention relates generally to hand tools and more particularly to tools of a combined nature, such as a combined hammer and punch.

The object and general nature of this invention is the provision of a combined hammer and punch in which the punch is swingable from an operating position over into engagement with the head of the hammer to an inoperative position where the point of the punch is enclosed. Another feature of this invention is the provision of a combination tool of the type just mentioned in which the punch element in its operative position is aligned with the axis of the hammer head.

A further feature of this invention is the provision of a hammer having a punch pivoted to the hammer head and swingable into an inoperative position in which the point of the punch is received in a recess in the hammer head. An additional feature of this invention is the provision of means serving as detent means for holding the punch in either of its positions.

An additional feature of this invention is the provision of a curved arm pivoted at one end to the head of a hammer in such a position that the other end of the arm lies substantially fiat against the striking face of the hammer head, the flat portion of the arm carrying a punch, with detent means acting against the pivoted portion of said arm and disposed in a recess formed in the hammer head.

Still further, another feature of this invention is the provision of a combined punch and hammer, in which the punch may be swung from one position to another by the same hand that holds the hammer, thus permitting the operator to employ one hand to hold onto a scaffolding or other support and to use the hammer changing the punch as desired with the other hand.

These and other objects and advantages of this invention will be apparent to those skilled in the art to which this invention appertains after a consideration of the following detailed description of the preferred embodiment, taken in conjunction with the accompanying drawings illustrating said embodiment.

In the drawings:

FIG. 1 is a side view illustrating a hammer in which the principles or" my invention have been incorporated, certain portions being broken away, the punch being shown in its operative position.

FIG. 2 is a view similar to FIG. 1, showing the retracted or inoperative position of the punch.

PEG. 3 is an enlarged detail view of a portion of the hammer shown in FIG. 1.

Referring now to the drawings, the hammer head 2 is of generally usual construction, having an eye 3 receiving a handle 4-, a poll portion 5 formed with a striking face 6. A slot 7 is formed in the poll portion 5 in any suitable Way, as by a milling cutter or the like, and a pivot pin 8 is disposed with its ends in a transverse bore formed in the hammer head generally at right angles to the plane of the slot 7.

A mounting part in the form of an arcuate arm 16 is formed with an eye 11 encircling the pivot 8. The arm is slightly resilient and is shaped so as to pass around the end of the poll 5 and lie substantially fiat against the striking face 6, this portion of the arm 10 being flat, as indicated at 13 and supporting a sharpened and hardened punch 14 that extends substantially perpendicular to the flat portion 13. The resiliency of the arm 19 holds the flat portion 13 firmly in substantially fiat contact against 3,16%,255 Patented Feh. 16, 1965 the striking face 6. From FiG. 1 it will be seen that the parts are so constructed and arranged that the punch extends substantially in alignment with the axis of the hammer head so that the punch is lined up with the center of percussion of the hammer head.

The punch-carrying arm it is swingable from its operative position (FIG. 1) to its inoperative or retracted position by movement about the pivot 8, shown in FIG. 2. From this figure, it will be seen that in the retracted position the arm ltl lies partially in the slot 7 and the sharpened end of the punch 14 lies in a recess 16 formed in the adjacent portion of the hammer head 2 by a suitable tool.

Means is provided for releasably holding the punch arm it) in either of its positions, such means taking the 'orm of a spring biased plunger 13 having a shank 19 disposed within a spring Zli carried in a bore 21 drilled in the hammer head. The outer end of the plunger, which may be formed as a ball, engages the outer surface of the eye it of the punch arm 19. The outer surface of the eye is not precisely circular but has What might be termed flattened or cam sections so shaped that the spring biased plunger 18 acts to hold the punch in either of its positions. The cam sections are shown at 22 in FIG. 3. Also the shape of the arm 10 itself, especially at the portion where the arm passes around to the striking face 6, is such that the resiliency of the arm cooperates to hold the punch in its operative position, FIG. 1.

Having described the preferred form of my invention, what I claim and desire to secure by Letters Patent is:

1. A combination tool comprising a hammer having a head with a striking face and a handle receiving portion, a handle fixed therein, a punch swingable between first and second positions and including a mounting part and a hardened point fixed to the mounting part, and means pivoting the mounting part to the hammer head, the hardened point extending outwardly from the striking face of the hammer head and in alignment with the gen erally central part thereof when the punch is in its second position, the mounting part including means engageable with the striking face to hold the hardened point in alignment.

2. A combination tool as defined in claim 1, further characterized by said pivot means being disposed adjacent one side of the head of the hammer inwardly of the striking face, and said mounting part being curved between said pivot means and said point so as to clear the adjacent portions of said hammer head and to dispose said point in said position of alignment.

3. A combination tool comprising a hammer head including a handle-receiving eye and a poll terminating in a striking face, there being a slot formed generally lengthwise in the poll of the hammer head and extending to a point adjacent the striking face of the head, a mounting part pivoted adjacent its inner end to said head adjacent the outer end of said slot and carrying a punch element at its outer end, said mounting part being shaped to pass from said slot around to a point lying substantially flat against the striking face of the hammer head in the operative position of said punch, said punch extending normal to the portion of said mounting part that lies substantially flat against said striking face, said mounting part being swingable into an inoperative position in which a portion of said part lies within said slot, and means adjacent the inner end of said slot forming a socket to receive the point of said punch in the inoperative position of said mounting part.

4. A combination tool as defined in claim 3, further characterized by spring biased detent means carried by the hammer head and acting against said part for holding the latter in either of its positions.
